Abstract

Abstrak: Sampah organic rumah tangga yang dihasilkan oleh masyarakat Desa narmada belum dikelola menjadi suatu produk yang bernilai ekonomi. Produk sampah organik dibuang begitu saja di lahan terbuka, di sungai atau dibakar. Karena itu, kegiatan pengabdian ini bertujuan untuk memperkaya pengetahuan sasaran penerima manfaat dalam rangka membangun motivasi masyarakat untuk mengelola sampah organic rumah tangga menjadi kompos yang bermanfaat. Kegiatan ini dilakukan di Desa Narmada, Kabupaten Lombok Barat. Sebagai masyarakat penerima manfaat adalah ibu rumah tangga dari kelompok PaManSam “Pangolah dan Pemanfaat Sampah”. Aktivitas kegiatannya meliputi: 1) penyuluhan tentang peran dekomposer dan proses pengomposan; 2) pembelajaran teknis pembuatan dekomposer lokal dan pengomposan sampah organik. Hasil kegiatan tersebut menunjukkan bahwa 1) 60% dari peserta memberikan respon yang positif terhadap materi penyuluhan yang diberikan; 2) peserta menguasai materi penyuluhan dengan baik, sehingga diharapkan dapat memotivasi mereka untuk mengurangi volume sampah dengan program-3R (reduce, reuse, recycle) mulai dari sumbernya; 3) secara umum, peserta dapat membuat dekomposer lokal dan mengaplikasikannya dalam proses pengomposan.Abstract:  Household organic waste produced by the people of Narmada Village has not been managed into a product that has economic value. Organic waste products are simply dumped in open fields, in rivers or burned. Therefore, this service activity aims to enrich the knowledge of target partners, housewives, in order to build their motivation to manage household waste into useful compost. The activity was conducted in Narmada, west lombok regency. The beneficiary partners are housewives from the PaManSam“Pangolah dan Pemanfaat Sampah” group. Activities include: 1) counseling on the role of decomposers in composting 2) the practice of making local decomposers and composting organic waste. This result shows that 1) 60% of the participants gave a positive response to the extension materials provided; 2) 50% of the participants master the extension material well, so it is hoped that it can motivate them to reduce the volume of waste with the 3R program (reduce, reuse, recycle) starting from the source; 3) generally, the participants can make local decomposers and apply it in composting.

Abstract

This study aims to examine the effect of the application of compost and biochar on the bacterial population in the rhizosphere and the growth of upland rice (Oryza sativa L.). and analysis of chemical and biological properties in the laboratory of chemistry and soil fertility, Faculty of Agriculture, University of Mataram. The soil used in this study had a pH value of 5.0 and available-P had 0.95 ppm, total N was 0.19%, K-exchanged was 0.22 meq/100g. C-organic value is only 1.2% and cation exchange capacity value (17.43 meq/100 g soil). the administration of doses of urea and phonska fertilizers combined with the provision of compost and biochar had an effect on the variables of plant height, number of tillers and leaf width where the P1 treatment gave a significant value compared to the P0 and P2 treatments. Parameters of root weight and stem weight in treatment P1 were more significant than those in treatment P0 and P2. In the variable total microorganisms with the number of bacterial colonies, phosphate solubilizing bacterial colonies and phosphate solubilizing fungal colonies had a significant value in the P1 treatment, in the respiration parameters of microorganisms p1 had a significant value with an average value of 4.36 mg C-CO2 / g soil.

Abstract

People's gold mining in Sekotong, also known as Unlicensed Gold Mining (PETI), causes environmental pollution problems because located at the surrounding community processes gold using the amlagamation technique with the help of mercury (Hg) in binding gold. Mercury waste discharged directly into the environment could have adversely affects public health and degrades soil and water quality. The presence of mercury in the soil is strongly influenced by soil characteristics, one of which is soil physical properties. The purpose of this study was to determine the relationship between the physical characteristic ustifluvents Entisol soil of Sekotong soil and mercury content at 0-20 cm soil depth. This research was conducted using descriptive method with survey technique. Soil sampling was conducted at 3 location points near the logs and tailling at a depth of 0 - 10 cm and 10-20 cm, each location point was replicated 3 times. The selection of soil sample points was based on contour differences that affect the proportion of mercury content at each soil depth. The results showed that the highest mercury content was at point 3 with an average value of 0.3089 ppm and there was a strong to very strong relationship between soil physical properties and Hg content.
